4 Claims. (Cl. 816) This invention relates to a vise, particularly adapted for use by watchmakers, and in particular, a base having a stationary jaw with spaced openings therein extended upwardly from one end, a coacting jaw movably mounted by a stock on the base and also having spaced openings therein with means for clamping the movable jaw through the stock thereof to the base and with a thumb screw and disc combination for forcing a watch assembly from a case, particularly of the waterproof type. a

The purpose of this invention is to provide a relatively small vise for holding a watch case as the back of the watch is removed therefrom and which is also adapted to hold the watch case as the interior of the watchfis forced therefrom and replaced therein.

Because of the relatively thin material of a watc case, it is difiicult to positively grip and hold a case as a back is unscrewed or removed therefrom without distorting the case and, with a watch case slightly distorted, it is substantially impossible to replace a back or the interior assembly of the watch. Withthis thought in mind, this invention contemplates a vise for gripping and holding a watch case wherein both a stationary jaw and a movable jaw of the vise are provided with spaced openings positioned to receive ears extended from a watch case, such as a case of a wrist watch and wherein with the ears extended into the openings of the jaws the case is adapted to be rigidly held as the back thereof is removed and as the interior assembly is removed and replaced.

The object of this invention is, therefore, to provide a vise for holding a watch case as the back is removed and i replaced in which the case is rigidly held without danger of distortion therein.

Another object of the invention is to provide a vise for holding a watch case in which the vise is readily adjustable to correspond with watch cases of different types.

Another important object of the invention is to provide a vise for gripping a watch case in which means is provided for forcing the interior of a watch from and into a case.

A further object of the invention is to provide a watch case gripping vise in which the vise is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies an elongated plate providing a base with one end extended upwardly forming a stationary jaw, a stock having an elongated slot therein positioned on the base and having an end extended upwardly to provide a movable jaw, a pivot pin extended through the slot of the stock of the movable jaw and being secured in the base of the stationary jaw, a stud secured in the base of the stationary jaw, also extended through the slot of the stock of the movable jaw, and having a thumb nut thereon, and a thumb screw threaded in a bushing in the base of the stationary jaw and having a disc on the extended end, the disc being positioned to register with the interior of a watch case .ice

clamped between the movable and stationary jaws of thervise. V t I a I V I Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a side elevational view of the improved watch vise with the movable jaw of the vise shown in one position in full lines and in another 'position in dotted lines and with a watch positioned between the jaws also shown in dottedlines.

Figure 2 is a plan view of the vise as shown in Figure 1 also showing a watch clamped between a movable and a stationary jaw of the vise with the watch shown in dotted lines and also showing the movable jaw in one position in full lines and in another position in dotted lines.

Figure 3 is a longitudinal section through the vise taken on line 3-3 of Figure 2, the illustration of the watch case being omitted.

Figure 4 is a cross section through the vise taken on line 4-4 of Figure 1 showing the stationary jaw on one end of the base of the vise. I

, Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved watch vise of this invention includes a base 10 having a stationary jaw 11 extended upwardly from one end, a stock 12 having a movable jaw 13 extended upwardfrom one end, the jaw 13 being positioned to coact with the stationary jaw 11, a pivot pin 14 extended through a slot 15 in the stock 12 and having an enlarged head 16, a

threaded stud 17 threaded into the base 10 and also extended through the slot 15, a thumb nut 18 positioned on the stud 17 and having a washer 19 adapted to straddle the slot 15, and a thumb screw 20 having a knurled head 21 on one end and a disc 22 on the opposite end threaded in a bushing 23 mounted, such as by a press fit, in an opening 24 in the base 10 and positioned wherebytthe disc 22 is between the stationary jaw 11 and the movable jaw 13. i

As illustrated in Figure 4, the stationary jaw 11 is provided with spaced openings 25 and 26 that are positioned to receive ears 27 and 28, respectively, of a watch case 29 and the jaw 13 is provided with similar openings 30 and 31 that are positioned to receive corresponding ears 32 and 33, respectively, on the opposite side of the watch case, the watch case and broken lines. a v

One side 34 of the stock not the movable jaw is provided with an arcuate surface 35 whereby the jaw 13 with the stock upon which the jaw is mounted are adapted to be rotated'in a clockwise direction about the pivot pin 14 to open the jaws to facilitate inserting watch cases in the jaws and also to facilitate removing watch cases from the vise.

Because of the very small size of the wrist band connecting ears on opposite sides of a watch case it is difficult to insert the four ears at the same time and for this reason the extended end of one of the sections of the stock 12 is cutaway providing an arcuate surface 35 which is adapted to slide against the threaded stud 17 to permit rotating the stock 12 about the pivot pin 14 so that the jaw 13 may be opened to a slight angle to permit the ears 27, 28, and 33 being inserted in the notches or slots and with these cars in the notches the stock 12 is turned back to the position shown in Fig. 2 whereby the car 32 may enter the slot 30.

The disc 22 is provided with a concave upper surface, as indicated by the numeral 36, to facilitate engagement thereof with the interior assembly of the watch.

With the parts formed in this manner, the watch vise is readily adjusted to watch cases of different sizes and ears being shown in with a watch case gripped between the jaws, as illustrated Operation The watch vise of this invention is positioned upon a watchmakers work bench and with the jaw 13 moved away from the jaw 11 a watch case is'positioned between the jaws with the ears 27 and 28 extended into the openings26. and 25 respectively and as the jaw13 is returned tothepositi'on shown in Figs. .1 and 2 the ears on the up posite side .of the watch case are inserted in the openings or recesses 30 and31 and the stock 12 is then moved toward the endof the vise in which the watch case is positioned and the watch case issecured in position in the vise by tightening the thumb nut 18. With the watch case firmly clamped between the jaws 11 and 13 both the face and back are adapted to be rotated in counterclockwise direction whereby these parts may be readily removed. With the frontand backof the watch case removed the threaded stud 20 is rotated by the knurled neaa ZI-Wh'ereb'y the' disc '22 forces the clock works assembly from the case.

It will be understood that modifications, within the scope ofthe'appended claims, may be made in the design andarangement of the parts without departing from the spirit of the invention.
